Jarret Greenbrier County Virginia/West Virginia

I came across this marriage. Michael Duffy & Rosannah Jarret 1 Oct 1823 Greenbrier County Virginia/West Virginia Searching for information on the husband of Rosannah Jarret. I found her listed on the 1830 census Greenbrier County as the head of the house,too bad that year did not list if she was a widow. Any information you may have will be very helpful to my research. Thank you Betty Jane Perkins
